    摘要: There is provided an exhaust gas treatment system including a CO2 recovery unit with further enhanced energy efficiency. The exhaust gas treatment system (1) includes: a CO2 recovery unit (10) including a CO2 absorption column (11), an absorbing solution regeneration column (16), a condensate supply pipeline (15) for supplying condensate, which contains CO2 absorbing solution discharged from the CO2 absorption column (11) to a bottom portion of the absorbing solution regeneration column (16), and a CO2 separation section (22) for performing heat exchange, via a heat exchanger (23), between the CO2 discharged from the absorbing solution regeneration column (16) and the condensate; and an exhaust gas heat exchanger (5) provided on a gas upstream side of the CO2 recovery unit (10) for performing heat exchange between exhaust gas before flowing into the CO2 recovery unit (10) and the condensate.

    摘要: To include an absorber (1006) that brings CO2 absorbent that absorbs CO2 contained in flue gas (1002) into contact with the flue gas to remove CO2 from the flue gas, a regenerator (1008) that strips CO2 from CO2 absorbent (rich solution), which is fed from the absorber through a first feed line L1 and has absorbed CO2, to regenerate CO2 absorbent, thereby acquiring regenerated CO2 absorbent (lean solution) (1009), falling film reboilers (1101-1 and 1101-2) that draw off CO2 absorbent (amine solution) (1033) from near the bottom of the regenerator and reheats regenerated CO2 absorbent via steam (1031), a first liquid-vapor separator (1103) that separates the CO2 absorbent reheated by the falling film reboilers into regenerated CO2 absorbent in which CO2 has been removed and vapor containing CO2, and a second feed line L2 for supplying the separated regenerated CO2 absorbent to the absorber.
